SEALING APPLIANCE.

Application filed June 3, 1919.

To all whom it may concern.

Be it known that I, AMOS GALLESON, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Sealing Appliances, of which the following is a specification.

My present invention is an improvement in the kind of closure-aflixing instrumentality for bottle sealing machines set forth in my Patent No. 1,299,551 in which a plastic elastic material, as rubber, forms a cushion for the throat forming series of segments,

the principal object of the present invention being to improve the action of the parts and more particularly of the segments and cushion, especially so that the segments will not be unduly free to tilt or rock as the bottle and closure perform their thrust movements. In my patented construction the rubber of the cushion was allowed to flow longitudinally of the axis of the throat when the segments were displaced outwardly, being for that purpose cut away at top and bottom to form spaces, and this led to a susceptibility of the segments to tilt or rock as the bottle head performed its thrust movements in the throat which in the present instance I very materially and advantageously reduce by opposing flow of the rubber in the longitudinal direction and providing for such fiow only in a direction transverse of the axis of the throat, as radially inward oroutward or circumferentially.

In the accompanying drawing,

Figure 1 shows in vertical section the sealing or closure-affixing head of a bottle sealing machine provided with my improved closure-affixing instrumentality;

Fig. 2 is a horizontal sectional view on the line 22, Fig. 1;

Figs. 3 and 4 show horizontal sectional views of modifications; and

Fig. 5 is a vertical sectional view of a closure affixing appliance constructed according to my invention and so as to be unitary in character.

The sealing head shown in Fig. 1 includes a housing for the closure-affixing instrumentality, such housing in the present instance being formed by the enlargement a on the lower end of the tubular stem b and a cup-shaped holder 0, which is fitted from below over the enlargement a and secured thereon by the pin (Z, the holder having an opening e to admit the bottle head and clo- Specification of Letters Patent.

sure which is alined with the bore of the tubular stem 7). The lower end of the stem 12 and the upper face of the flange f of the holder 0 form broad contact faces which are preferably though not necessarily horizontal.

g designates an annular expansible throatforming series ofsegments, preferably made of hardened metal and substantially the same as in my patent aforesaid. The annular series being of greater diameter than the opening 6, said series is held between the lower end of the stem 6 and the flange f of the holder 0, fitting snugly, but so as to freely slide radially, between them.

Cushion means composed of elastic plastic material, such as rubber h, is arranged radially outward of each segment and between the same and the part of the housing aforesaid radially outward of each such segment, which part of the housing forms an unyielding abutment z for the cushion means. Preferably when the series of segments are in their contracted state the cushion means it fills the space between the series of segments and the abutment 2'. Further, the cushion means 72, is confined against vflow vertically, that is, longitudinally, of the axis of the throat formed by the segment series, as by having its top and bottom surfaces formed to bear fiat against the opposed surfaces of stem 6 and flange f. In the form of the cushion means now being described it is endless (Fig. 2). To permit the flow of the material of the cushion means it when the series of segments are expanded, as by the introduction of a bottle head and closure thereinto, radial recesses j may be formed in the series of segments 9, in the present instance extending from top to bottom thereof.

In Fig. 3, where the construction is otherwise substantially the same as in Figs. 1 and 2, the flow of the material of the cushion means when the series of segments are expanded is adapted to be radially outward, as into radial recesses 72 formed in the abutment 2', and in the present instance extending from top to bottom thereof.

In Fig. 4 the flow of the material of the cushion means is allowed to be circumferential, as by forming the cushion means in segments Z which are spaced from each other more or less so that each can expand in the circumferential direction; any means for preventing the segments Z from creeping circumferentially out of place may be provided, as the projections m, for example, formed on the inside of the housing and in the present instance extending from top to bottom thereof. In all the instances above described, the material of the cushion is confined against flow longitudinally of the axis of the throat, though in each instance it is allowed to take place in a direction transverse of said axis.

In the unitary form of the device constructed according to my invention as shown in Fig. 5 the annular series of segments a and elastic plastic material 0 forming a radially outward cushion for each segment are contained in an annular shell 7). The shell having initially been formed with an inturned flange 9 at one end and with its other end or edge left in the cylindrical state (dotted lines), the series of segments and cushion means are forced into the same, whereupon the said end or edge of the shell is bent down to form an inturned flange 1", the two flanges bearing square against the flat ends of the cushion means and somewhat overlapping the segments; preferably the body inclosed by the shell and comprising the cushion means and segments is provided with rabbets s at top and bottom to receive the flanges g r so as to produce a flush surface at the top and bottom of the appliance, suitable space 6 being left to allow for the expansion of the segments. The flow of the elastic plastic material 0 is in this instance illustrated by way of example as being allowed to take place radially outward, i. 6., into the holes a formed in the shell. of thedevice is adapted to be fitted into the housing, occupyin the same position therein as the parts g 2 shown in Fig. 1.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In combination, with an annular expansible throat-forming series of segments, cushion means for each segment arranged radially outwardly thereof and composed of elastic plastic material, such cushion means being free to flow in a direction transverse of the axis of the throat when subjected to pressure, and means to house said segments and the cushion means, the same forming an unyielding abutment for the cushion means radially outwardly opposed to each segment and confining the cushion means against flow longitudinally of the axis of the throat.

2. A sealing-throat device for a bottle sealing machine including, in combination, an annular expansible throat-forming series of segments, cushion means for each segment arranged radially outwardly thereof and composed of elastic plastic material, and a shell extending circumferentially around the cushion means and having its edge portions inturned and overlying the cushion means and segments.

In testimony whereofI aifix my signature.
